Claims

[Claims for Utility Model Registration] (1) A vacuum container connected to a vacuum pump and capable of depressurizing to a predetermined degree of vacuum, and a vacuum container disposed on the upper end surface of the vacuum container, on which the container to be depressurized is placed. a table that is suitable and has at least one intake pressure supply hole formed therein; an intake pressure supply pipe connecting the vacuum container and the intake pressure supply hole of the table; and an on-off valve provided in an intake pressure supply passage leading to the intake pressure supply hole via the intake pressure supply hole. (2) The vacuum container has a cylindrical shape with a sealed bottom opening and a flange formed in the top opening, and the table is in close contact with the top surface of the top opening flange of the vacuum container at the peripheral edge of the bottom surface. By doing so, the upper end opening of the vacuum container can be sealed, and the table further includes an air intake pressure that extends from the intake pressure supply hole on the upper surface to the intake pressure supply pipe connection hole on the peripheral wall surface through the inside. A supply pipe is formed, one end of the intake pressure supply pipe is connected to the intake pressure supply pipe connection hole, and the intake pressure supply pipe of the table forms a part of the intake pressure supply pipe. The reduced pressure dispensing device according to claim 1, characterized in that it is a.
